My wife Emily and her sister Juliette did the singing. I played the instruments, which were: concert ukulele, soprano ukulele, old Yamaha keyboard on "jazz organ" setting, banjo, mandolin, Yamaha Electone organ, tambourine, cowbell, piano, tone block, newer Panasonic keyboard on "acoustic bass" setting, hand drum, glockenspiel, and some clapping.
